Plastics will continue to be required in space applications from rockets to vehicles for landing on other planets. The space structures, reentry vehicles, and equipment such as antennas, sensors, and an astronaut s personal communication equipment that must operate outside the confines of a spaceship will encounter bizarre environments. Temperature extremes, thermal stresses, micrometeorites, and solar radiation are sample conditions that are being encountered successfully that include the use of plastics. 

Poly(butylene terephthalate) (PBT) (1) resins are semicrystalline thermoplastics used in a wide variety of applications, most commonly in durable goods that are formed by injection molding. Applications include electronic and communications equipment, computers, televisions, kitchen and household appliances, industrial equipment, lighting systems, gardening and agricultural equipment, pumps, medical devices, food handling systems, handles, power and hand tools, bobbins and spindles, and automotive parts in both under-the-hood and exterior applications. Additionally, PBT is very widely used to form electrical connectors. PBT, through its many blended products, can be tailored to suit numerous applications. 

In 1990, Sanyo and Matsushita initiated large-scale commercialization of small sealed nickel-metal hydride batteries. They are now joined by Dur-acell, Toshiba and Varta in a consortium which is known as the 3C alliance (camcorders, cellular telephones and computers). Several plants have been commissioned which are each producing 100-200 million cells per annum. It is forecast that nickel-metal hydride may overtake nickel-cadmium before the end of the century. In addition to the 3Cs nickel-metal hydride cells are used for a wide variety of cordless consumer products, communications equipment and other high rate long cycle life applications. 

Applications of Ni/MH batteries include computers, camcorders, cellular phones, communication equipment, variety of cordless consumer products, high rate long cycle life applications, electric vehicles (under development), and so on. Ni/MH batteries are more environmental friendly than Ni/Cd batteries, and they are easy to dispose. Disadvantages of Ni/MH batteries include lower rate capability, poorer charge retention, and less tolerance for overcharge than Ni-Cd batteries. Like Ni/Cd batteries, Ni/MH batteries are also subject to the memory effect a description of this phenomenon can be found in Sect. 7.9.2.2. 

Typically, a low molecular weight solid epoxy resin and latent curing agent, such as dicyandiamide dissolved in an appropriate solvent, are widely used in dry lay-up formulations for electrical laminates for computers, aerospace applications, and communications equipment. Wet lay-up systems are almost exclusively based on low-viscosity resins cured with aliphatic amines. These ambient cure resin systems are used primarily for manufacture of large chemical-resistant tanks, ducting, and scrubbers. Filament winding is used... 

Zinc in alloyed form can be cast with fine detail into complicated shapes and can be formed with extra thin walls (0.5 mm). Specifiers can choose from a family of zinc alloys and a range of casting processes that are the most suited for their products. Zinc alloy castings are unique, particularly when produced by the pressure die-casting process. They can be made to extremely close tolerance, with excellent surface finish, have a range of useful physical and mechanical properties and can receive a wide range of applied finishes. Typical applications are precision parts for vehicles, aircraft and communications equipment, plumbing hardware, construction fixtures, household appliance, zippers and toys. 

Applications and uses surgical probes, pharmaceutical process equipment manifolds, high-frequency insulators used in microwave communications equipment, clamps used to connect printed circuit boards to video display units used in airplanes, tanks, and ships. 

Industry and Business. Although the civilian population is a significant consumer of microwave equipment, commercial and military applications represent a large market share. In the commercial sector, the civilian aircraft and shipping industries are major purchasers of microwave equipment. The National Aeronautics and Space Administration (NASA) requires extremely precise, complex, and expensive navigational and communications equipment for its... 

The technology developed for radio astronomy is virtually the same as that used for commercial communication receivers. Therefore, many of the advances in radio astronomy have commercial applications in the form of smaller, more sensitive, and less expensive satellite communication equipment. Many satellite communication companies keep abreast of the developments in radio astronomy technology to adapt this technology to produce better communication systems. 

Microphone types can be roughly divided into two basic classes those intended for professional applications, such as broadcast stations and recording studios, and those designed for industrial applications, such as communications equipment and special purpose audio pickup where faithful audio reproduction is not the primary concern.

Molded ABS parts are used in both decorative and protective applications in communications equipment like telephones (see Fig. 6-3), and for appliances, business-machine housings, safety helmets, camper tops, pipe fittings, shoe heels, and so on. Chrome-plated ABS has replaced die-cast metals in plumbing hardware and auto grills, wheel covers, and mirror housings. Some typical products vacuum-formed from extruded ABS sheet are refrigerator liners, luggage shells, tote trays, mower shrouds, boat hulls, and recreational vehicle parts. The possible extruded shapes include weather seals, conduit, pipe for drain-waste-vent (DWV) systems, and the like. 

These epoxy blends are often used in high-frequency applications including antennas, radio frequency (RF), and wireless communications equipment, and high-speed computing applications.

Apart from domestic applications, a need for new, improved power sources of small size also arose in different portable devices to be used in the military sector, such as night-vision devices and individual communication equipment. 

Zn-AgO batteries are widely deployed in space application because of their outstanding electrical performance capabilities. These batteries have been used by the astronauts of several missions in their extravehicular activities because of their high-energy capability and portability aspects. These batteries can be used in portable applications, such as television cameras, medical equipment, communications equipment, and lighting systems. 

Typical applications include consumer electronics devices, military communications equipment, transportation, automatic meter reading, medical defibrillators, and memory backup. 

Potential applications include military search and rescue communications equipment, some industrial systems and transportation.
